I am trying to build a SMPS without a power integration IC(e.g tny267) . I'd actually like to build the one in image.but I am not good at drawing schematic by tracing the connections. I searched online but couldn't find anything. So , if anyone could help me with a schematic I would really appreciate that .
the bigger transistor on the board is MJE13003, the smaller one is SS9014 and the 4 pin ic on side a rectifier.
The red arrows indicate mains connection points and blue ones indicate output point
